In 2016, after the death of the US Supreme Court Justice Antonin Gregory Scalia, several Republicans claimed that then-President Barack Obama should not seek a replacement, since they were in an election year.
Among them Senators Ted Cruz, Lindsey Graham and Mitch McConnell.
But after the death of Ruth Bader Ginsburg on Friday, these politicians advocate that Donald Trump seek a candidate "in extremis", just before the November elections.
